Study Notes

Tool Control Procedures

Tool control programs enhance safety by ensuring tools are accounted for after maintenance tasks.
Each tool should have a designated storage area for quick identification if a tool is missing.

Tool Storage and Control Methods

Tool Shadowing: Tools are outlined in storage areas to highlight missing items, commonly using foam cutouts or pegboards.
Tool Identification: Utilizes methods such as colored tape, vibra-peening, laser marking, and RFID systems for tracking ownership.
Recommended not to use permanent markers for identification, as effectiveness is limited.

Employee Ownership and Accountability

Marking personal tools with mechanics' initials is preferred; avoid company-specific numbers that may require re-marking if an employee changes jobs.
Tool marking helps ensure tools are returned if lost and promotes vigilance in reporting missing items.

Tool Inventory and Reporting

Conduct regular tool inventories, ideally after each task or daily shifts, to quickly identify any missing tools.
A clear missing tool reporting system enhances accountability and ensures a safe working environment.

Measuring Tools

Dial Indicator: Used for measuring the roundness of components like crankshafts, precise to thousandths of an inch.
Micrometer Caliper: Preferred for precise measurements (e.g., 0-1 inch micrometer).

General Purpose Tools

Hammers and Mallets: Metal-headed hammers are typically weight-classed; soft-faced hammers prevent damage to surfaces.
Screwdrivers: Must match the screw type for proper function; incorrect sizing can damage screws and tools.
Pliers: Common types include diagonal, needle nose, and duckbill. Each has specific uses in gripping and cutting.

Punches

Punches are usually made from carbon steel and assist in marking locations for drilling or cutting.
Two types: solid and hollow. Prick punches are used for reference marking; center punches keep drill bits from wandering.

Wrenches

Made predominantly from chrome-vanadium steel for durability; types include open-end, box-end, and combination wrenches.
Socket and Ratchet: Allows for efficient turning of nuts or bolts, with varying socket designs to fit different heads.
Adjustable Wrench: Versatile tool with smooth jaws to minimize fastener rounding.

Special Wrenches

Crowfoot Wrench: Used in tight spaces where regular wrenches can't fit.
Flare Nut Wrench: Designed for hydraulic lines and can be used with torque wrenches for accurate tightening.

General Safety and Usage Practices

Always use the correct size tools to avoid damaging fasteners.
Hold parts securely in a vice rather than by hand when using screwdrivers to prevent potential injury from slips.
Ensure tools like punches are not struck with excessive force to avoid damage.### Aircraft Specific Shop Tools
Phillips, Torx, Security T, Allen Wrench/Key
Various screw types and associated tools for fastening.
Universal Propeller Protractors
Measure angles in degrees; useful for determining the travel of ailerons, elevators, and wing flaps.

Drill Press

Functionality
Drilling holes with high accuracy; assists in the precise location and direction of drilled holes.
Table Adjustment
Height of the drill press table is adjustable to accommodate different part sizes; part must be properly clamped to avoid accidents.
Safety Precautions
Ensure parts are secured to prevent slipping; unfastened pieces may bind and cause injury.

Metal Bending Tools

Bar Folder
Used for bending edges of sheet metal.
Cornice Brake
Similar to a bar folder but allows for easier metal folding as it passes through the jaws without obstruction.
Box and Pan Brake (Finger Brake)
Equipped with removable steel fingers to create different bends; must ensure all fingers are securely tightened before use.

Power Equipment and Tools

Kett Saw and Pneumatic Circular Cutting Saw
Designed for cutting out damage on aircraft parts.
Die Grinder
Handheld tool that operates at high speeds, used for weld breaking, smoothing sharp edges, and general grinding; powered by compressed air or electric sources.
Cut-off Wheel
Thin abrasive disc for cutting aircraft skin and stringers; available in various sizes.
Squaring Shear
Utilizes a foot treadle to lower the upper blade for cutting materials.
Band Saw
Employs a continuous toothed band for cutting aluminum, steel, and composite materials.
Disk Sander and Belt Sander
Used for smoothing and polishing surfaces, more efficient than manual filing.
Portable Power Drills
Can be powered by electricity or compressed air; ensure proper technique and safety gear during use.
Pneumatic Drill Motors
Lightweight and ideal for repairs in flammable environments; recommended speeds of around 3,000 RPM for aircraft work.
Two Hole Drill Motors
Allows simultaneous drilling of two holes for nutplates, ensuring precision alignment.

Pneumatic Rivet Gun

Common Tool
Primarily used for rivet installation; operates at air pressures of 90 to 100 psi.
Rivet Installation
Riveting action should be performed within 1 to 3 seconds; requires proper pressure and alignments to avoid damage.
Safety Protocols
Avoid pointing the gun at anyone; always disconnect the air hose when not in use.
Rivet Headers
Available in various styles for accessing rivets in tight spaces; must be kept clean for optimal performance.

Special Riveting Methods

Compression Riveting
Applicable only in spaces where the reach is sufficient; hand or pneumatic methods can be employed.
Microshavers
Maintain the appearance of countersunk rivets within specific tolerances; critical for surface smoothness.
